Echeveria plant named ‘Fireglow’

ABSTRACT

A new and distinct  Echeveria  cultivar named ‘Fireglow’ is disclosed, characterized by multi colored rosettes with a warm, coppery tonality. Undulate, cupped foliage aspect, and distinctive metallic appearance. Excellent accent plant due to warm foliage tones.  Echeveria  is a popular genus, typically produced as container plants for the patio or as landscape plants, as a variety of ornamental purposes.

Latin name of the genus and species: Echeveria hybrid.

Variety denomination: ‘FIREGLOW’.

BACKGROUND OF THE INVENTION

The new cultivar, Echeveria ‘Fireglow’, is the product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented, seed parent, Echeveria ‘WA06RA’ with the pollen parent an unpatented, proprietary variety of Echeveria referred to as ‘New Pink 05’. The cross pollination was made during May 2011 in Vista, Calif., at a commercial greenhouse. The new cultivar ‘Fireglow’ was selected by the inventor, Renee O' Connell, in August 2012, in Vista, Calif. at a commercial greenhouse.

Asexual reproduction of the new cultivar ‘Fireglow’ was first performed in Vista, Calif., at a commercial greenhouse, by terminal vegetative cuttings in September 2012. Echeveria ‘Fireglow’ has since produced at least 9 generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Fireglow’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘FIREGLOW’. These characteristics in combination distinguish ‘FIREGLOW’ as a new and distinct Echeveria cultivar:

-   1. Multi colored resetting foliage of an overall warm, coppery     color. -   2. Echeveria ‘Fireglow’ forms rosettes with a slightly undulate     morphology. -   3. Shiny, metallic appearance to foliage. -   4. Lighter leaf margins, accenting the copper colored, shiny leaves     and creating the impression of “glowingly lit”. -   5. Echeveria hybrid ‘Fireglow’, because of its rich, warm-toned     coloration, as well as the very shiny, almost metallic texture of     the rosette, can be used as an excellent accent for succulent     “groupings” or dish gardens, as well as wedding bouquets, and     tabletop centerpeices for autumn festivities.

PARENTAL COMPARISON

Plants of the new cultivar ‘Fireglow’ are similar to plants of the seed parent in most horticultural characteristics. However, plants of the new cultivar ‘Fireglow’ differ in the following:

-   1. Echeveria ‘Fireglow’ exhibits an undulate morphology to the     rosette, whereas the rosette morphology of Echeveria ‘WA06RA’ is the     common “star” pattern of many other Echeveria rosettes. -   2. The leaves of the rosette of Echeveria ‘Fireglow’ are margined in     a lighter color, strongly accenting the shiny pink-copper leaves,     whereas the leaves of Echeveria ‘WA06RA’ have margins of the same     color as the rosette leaves. -   3. Echeveria hybrid ‘Fireglow’ exhbits leaves that are crinkled and     undulate margined, whereas the leaves of ‘WA06RA’ have smooth,     straight margins. -   4. The Echeveria hybrid ‘Fireglow’ exhibits a rosette color of     warm-toned coppery pink, whereas the rosette color of Echeveria     ‘WA06RA’ is a darker color, without the pink overtones.

Plants of the new cultivar ‘Fireglow’ are similar to the pollen parent in most horticultural characteristics. However, plants of the new cultivar ‘Fireglow’ differ in the following:

-   1. While Echeveria ‘Fireglow’ exhibits some of the pink coloration     of Echeveria ‘New Pink 05’, it also exhibits the copper color as     well, whereas as Echeveria ‘New Pink 05’ does not. -   2. Echeveria ‘Fireglow’ exhibits crinkly, light colored margins,     whereas the Echeveria ‘New Pink 05’ are crinkly, but are not light     colored. -   3. Echeveria ‘New Pink 05’ produces leaves that are longer and more     narrow in width thank those of Echeveria ‘Fireglow’. -   4. Echeveria ‘Fireglow’ exhibits a metallic, shiny texture to the     leaves that is not seen in Echeveria ‘New Pink 05’.

COMMERCIAL COMPARISON

The new cultivar ‘Fireglow’ can be compared to the unpatented commercial variety Echeveria ‘Perle van Nurnburg’. Plants of the new cultivar ‘Fireglow’ differ in the following:

-   1. Echeveria ‘Fireglow’ exhibits rosettes of coppery pink, whereas     those of Echeveria ‘Perle von Nurnberg’ are a lilac-mauve color. -   2. The leaves of Echeveria ‘Fireglow’ have a shiny texture, whereas     the leaves of Echeveria ‘Perle von Nurnberg’ have a matte, glaucous     texture. -   3. Echeveria hybrid ‘Fireglow’ produces a rosette with an undulate     morphology, whereas the rosette of Echeveria ‘Perle von Nurnberg’     exhibits a “star” shaped rosette.

The new cultivar ‘Fireglow’ can be compared to the unpatented commercial variety Echeveria ‘Afterglow’. Plants of the new cultivar ‘Fireglow’ are similar to ‘Afterglow’ in most horticultural characteristics. However, plants of the new cultivar ‘Fireglow’ differ in the following:

-   1. Echeveria hybrid ‘Fireglow’ produces leaves with a shiny,     metallic texture, whereas Echeveria ‘Afterglow’ produces matte,     glaucous leaves. -   2. Echeveria hybrid ‘Fireglow’ has a warm coppery rose colored     rosette as compared to the blue and purple rosette of Echeveria     ‘Afterglow’. -   3. Echeveria hybrid ‘Fireglow’ produces leaves with cupped,     undulating margins, whereas the leaves of Echeveria ‘Afterglow’ have     smooth margins.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs in FIG. 1 through FIG. 2 illustrate in full color typical plants of ‘FIREGLOW’ grown in a greenhouse in Vista, Calif. The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of the new Echeveria plant. The following photographs depict plants grown under two different natural light conditions. Temperatures ranged from approximately 10° C. to 38° C. night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.

FIG. 1 illustrates in full color a typical of plant of Echeveria ‘Fireglow’ grown in a greenhouse in Vista, Calif. under moderate light conditions of approximately 2000 to 3000 foot candles. The flowering stem observed in the photo aborted and did not produce flowers.

FIG. 2 illustrates in full color typical of plant of Echeveria ‘Fireglow’ grown in a greenhouse in Vista, Calif. under high light conditions above 4000 foot candles.
